Abstract

The present invention includes compositions and methods for reduce the taste of the drug in the drug resin complex. The composition may include one or more drug-resin complexes and a highly compressible, free-flowing pharmaceutical excipient. The resin is present in an amount effective to reduce the taste of the drug in the drug resin complex relative to an otherwise identical pharmaceutical composition without the resin; and wherein the highly compressible, free-flowing pharmaceutical excipient causes release of the drug-resin complex in the mouth.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A compressed, orally disintegrating, controlled release taste-masked pharmaceutical composition comprising:
 a coated drug-ion-exchange resin complex and a directly compressible, free-flowing pharmaceutical excipient, 
 wherein the composition effectively masks an unpalatable taste associated with delivery of the drug, 
 wherein the coated drug-ion-exchange resin complex is coated with a controlled release coating, 
 and wherein the directly compressible, free-flowing pharmaceutical excipient aids in the liberation of the coated drug-resin complex in the mouth through disintegration. 
 
     
     
       2. The composition of  claim 1 , wherein the drug in the drug-ion-exchange resin complex comprises dextromethorphan, codeine, morphine, hydrocodone, hyoscyamine, moguisteine, pseudoephedrine, chlorpheniramine, phenylprop anolamine, pharmaceutically acceptable salts of the same or combinations thereof. 
     
     
       3. The composition of  claim 1 , further comprising one or more flavorants, sweeteners, coolants, dyes, or combinations and mixtures thereof. 
     
     
       4. The composition of  claim 1 , further comprising one or more excipients, one or more binders or combinations and mixtures thereof. 
     
     
       5. The composition of  claim 1 , wherein the coated drug-ion-exchange resin complex comprises polistirex, polacrilex or combinations thereof. 
     
     
       6. The composition of  claim 1 , wherein the composition comprises pseudoephedrine polistirex and chlorpheniramine polacrilex. 
     
     
       7. The composition of  claim 1 , wherein the resin in the coated drug-ion-exchange resin complex comprises one or more cationic exchange resins. 
     
     
       8. The composition of  claim 1 , wherein the coated drug-ion-exchange resin complex comprises a divinylbenzene sulfonic acid cationic exchange resin. 
     
     
       9. The composition of  claim 1 , wherein the composition comprises a hardness of between about 5 and about 15 kPa. 
     
     
       10. The composition of  claim 1 , wherein the composition has at least about 20 percent better mouth-feel. 
     
     
       11. The composition of  claim 1 , wherein the coated drug-ion-exchange resin complex controlled release coating comprises a diffusion barrier coating. 
     
     
       12. The composition of  claim 11 , wherein the diffusion barrier coating is a time release coating. 
     
     
       13. A compressed, orally disintegrating, controlled release taste-masked hyoscyamine pharmaceutical composition according to  claim 1  comprising:
 a coated hyoscyamine-ion-exchange resin complex; and 
 a directly compressible, free-flowing pharmaceutical excipient that aids in the liberation of the coated hyoscyamine-ion-exchange resin complex in the mouth through disintegration. 
 
     
     
       14. The composition of  claim 13 , further comprising one or more flavorants, sweeteners, coolants, dyes, or combinations and mixtures thereof. 
     
     
       15. The composition of  claim 13 , further comprising one or more excipients, one or more binders or combinations and mixtures thereof. 
     
     
       16. The composition of  claim 1 , wherein the directly compressible, free-flowing pharmaceutical excipient comprises a water-soluble compressible carbohydrate. 
     
     
       17. The composition of  claim 1 , further comprising one or more amorphous sugars. 
     
     
       18. The composition of  claim 1 , further comprising a plasticizer. 
     
     
       19. The composition of  claim 1 , wherein said controlled release coating comprises a delayed release coating. 
     
     
       20. The composition of  claim 19 , wherein the drug in said drug-ion-exchange resin complex comprises an analgesic drug, anti-inflammatory drug, central nervous system agent, anti-hypertensive drug, or an anti-hyperactive drug. 
     
     
       21. The composition of  claim 20 , wherein the drug in said drug-ion-exchange resin complex comprises an anti-hyperactive drug. 
     
     
       22. The composition of  claim 19 , wherein the drug in said drug-ion-exchange resin complex comprises amphetamine. 
     
     
       23. The composition of  claim 1 , wherein the drug in said drug-ion-exchange resin complex comprises an analgesic drug, anti-inflammatory drug, central nervous system agent, anti-hypertensive drug, or an anti-hyperactive drug. 
     
     
       24. The composition of  claim 23 , wherein the drug in said drug-ion-exchange resin complex comprises an anti-hyperactive drug. 
     
     
       25. The composition of  claim 1 , wherein the drug in said drug-ion-exchange resin complex comprises amphetamine.
